To all whom it may concern:

Be it known that THOMAS K. KEITH, deceased, late a. citizen of the United States,

and resident of Boston, in the county of' Suffolk .and State of Massachusetts, did 1nvent .certain new and useful Improvements in Machines for Closin Bottle Ends with T in-Foil, of which the ollowing is a specification.

The object of the invention is to put around the necks of bottles a sheet of tin foil or the like, anopera-tion ,which has heretofore been done by hand. j

The invention is carried out as follows, reference being had to the accompanying drawings, where- Figure 1 is .a to plan View; Fig. 2 is a partial section on line 2-2 of Fig. 1; Fig. 3 is an end elevation; Fig. 4 is a perspective view of some of the linkage; Fig. 5 is a perspective view of the gri ping device; Fig. 6 is a perspective view of) the knives; Fig. 7 is a perspective view of the cam trip ing device; and-Fig. 8 is a detail of'punc ing disk mechanism.

Similar charactersrefer to similar parts wherever they occur on the different parts of the drawin s.

1 is the rame of the machine, supported on standards 2 2, and carrying a stationary shaft 3, upon whlch are rotatably mounted the driving wheel 4, clutch 5, and gear wheel 6. Shaft 3 also has rotatably mounted upon it a sleeve 7, which carries rigidly attached to it cams 8 and 9, for pur-poses hereinafter described. Drivin wheel 4 is connected to driving pulley 10, y, means of belt 11, and pulley 12, mounted on'shaft 13. Clutch 5 is en aged by forked lever 14, pivoted to standa 2 at 14", and operated by lever 16, pivoted to standard 2, at 15, through the agency of link 14a.

17 is a roll of tin foil of the proper width, loosely mounted on pin 18, secured to standard 2. From roll 17 the tin foil 19 is carried around two idler spools l20---21, thence over idler roll 22, secured tolthe glue pot 23,

and to idler roll 24, rubbing against the gluing roll 25 in passing, and thence'to the clamping jaws 26, 27. The clamping jaw 27 is secured to lever 28 rigidly mounted .on shaft 29, and is operated by cam oove 30, in cam 8, through the agency o lever 3l rigidly secured to said shaft 29.

Knives 32, 33, mounted respectively rigidly and loosely on shaft 34, serve to cut oil' the tin foil after `a portion sutncient for one bottle has been fed to the gripper. Knife 32 is operated b the linkage shown in Fig. 4, and consists o a short lever arm 35, rigidly attached .on shaft 34, and .carrying a. pin 36, which engages one end 37 ofA-a bent lever 38, loosely mounted on rod 39. The other end 40 of lever 38 carries 'a cam roll which engages cam 9. Knife 33 is operated bya rod 41, pivotally connected at its lower end to a rock arm 42, rigidly mounted upon rod 39, which rod has rigidly mounted upon it cam lever 43, which engages cam groove 44 in cam 8.

The gripper 45 is mounted upon a sliding plate 46,vand is form-ed with fingers which intermesh with those of the clamping jaws 26, 27, when sliding plate 46 'is movedforward, so thetin foil can be seized by the gripper and carried back with the receding plate 46, jaw 2- being automatically opened to release said .tin foil, after the gripperl 45 has seized it.

The movement of plate 46 is controlled by rock .arm 42, through the agency of rock arm 47, and link 48 pivotally secured to pla-te 46; said rock arm 42 being actuated by cam groove arm 47 is loosely pivoted to the frame at 49, and carries rigidly a latbar 50, upon the lower end of which idler spool 20 is mounted. It will be thus noted that spool 20 osj cillates while all the other spools and rolls 17, 21, 22, and 24 have stationary spindles.

44 as before described. Rock i The object of this oscillation is to reel oli' a new supply of tin foil from roll 17 while the gripper is advancing, and to create a slackness of same, when gripper is receding with the free end of the tin foil, thus lessen ing the strain and consequent tendency to tearing.

Rock arm 42 has pivotally attached t0 its upright arm 51, a ratchet arm 52, which engages with a ratchet wheel 53, rigicll. at.- tachcd to the spindle Awhich carries g uing roll 25.

54 is a scra ing device to control the quan- `-tity of glue ed to roll 25. Lever 2-8, which carries clamping jaw 27 has .also secured to it a second clamping plate 55, (see Fig. 6) which presses the foil against an abutment 56, on feed board 57. This abutment serves roc to keep tin foil 19 out of cont-act with feed board 57, so that it is suspended between roll 24, and abutment 56, and again between abutment 56 and clamping jaw 26.

The gripper 45 is pivotally mounted in two blocks 58 58, secured to plate 46, and is normally held in gripping position by coiled spring 59. (See Fig. 5.) When plate 46 is in its rearward position, the rear end 60 of gripper 45 has engaged the lug 61 on lever 62, and raised it from the normal position shown in Fig. 5. Lever 62 is pivoted to the frame 1 at 63, and carries near its free end a pin 64, which pin carries a bent lever 65, the free end of lever 65 passing .under the forward end of lever 16.

Gear 6 is enmesh with pinion 71, set screwed to hollow counter shaft 72, mounted, in standard 2,said shaft7 2 carrying rigidly at its outer end brush lever 7 3,upon which brush 74 is mounted. Within hollow countershaft 72 is slidably mounted a spindle 75, carrying at its outer end a punching disk 76. Disk 76 is held normally away from the standard 2 by coiled spring 77, and has on one edge a catch 78, which is engaged by the pawl of flat spring 79, when disk 76 is drawn in toward standard 2. Spring 79 is mounted on stud 80 in the boss on standard 2, and is normally held against pin 81 (also in bossl on standard 2) by coiled spring 82, but can be swung laterally by the lever 73, so as to release disk 76, returning against pin 81 `after lever 73 has passed by. Spindle 75 is flattened at its inner end to prevent turning and passes through an elongated hole in lever 14, and receives a pin 83.

The motion is as follows: When the forward arm of lever 16 is depressed, the clutch 5 is moved forward on shaft 3,and into engagement with gear 6. As driving wheel 4 1s constantly rotating, this sets pinion 71, rotating in the direction indicated by the arrow in Fig. 3. Pinion 71 c auses brush 74.

to rotate, and just before completing one revolution, lever 73 strikes spring 79, re. leasing catch 78 on disk 76. Spring 77 then projects the disk forward until pin 83 strikes lever 14 in its forward position. After lever 73 has passed, spring 79 returns to its normal position and upon releasing lever 16, spring 84 releases clutch 5, at the same time carrying back spindle 75 against spring 77, by means of pin 83.v As the disk 76 recedes the catch 78 will again enga e with the awl on spring 79, which will yie d sufficient y to permit of same.

Referring to Figs. 1, 2 and 7, it will be noticed that driving wheel 4 has a hub projecting from its rear face which receives rigidly a collar 85. U on this collar is ivotally mounted a doub e pawl 86, contrlled by .sprin 87. Adjacent to this collar is a washer 8, washer 89, likewise pinned to'shaft 3, prepinned to shaft 3. This withv vents longitudinal movement of the cams 8 and 9 on shaft 3. Cam 8 has on its front face a hub 90, in the edge of which is a notch 91, for engaging finger 92 of double pawl 86. The other finger 93 of pawl 86 is engaged at different times by finger 94 and lug 95 on plate lever 96. Plate lever 96 is pivotally connected at 97 to a strap 98 secured to frame 1, and is controlled by spring 99, and pin 100 in strap 98.

The operation is as follows z-When the clutch 5 is in its rearward or open position, the linger 92 of double pawl 86 (which is carriedbackward and forward with the clutch 5) is held upon hub 90 of cam 8, by spring 87, at a point back of notch 91, and revolves thereon freely without affecting the cams 8 and 9. When clutch is moved forward by depressing forward arm of' lever 16, the finger 92 moves forward sufliciently to leave hub 90 and then is held against the periphery of washer 86, by spring 87, revolving freely thereon as before. When pressure upon lever 16 is removed, the spring 84 acts to throw the clutch with the pawl 86 backward, but this is prevented for the moment by reason of the factthat said pawl abuts against the edge of hub 90. When, however, the continued revolution of pawl 86 brings finger 92 opposite notch 91, in hub 90, the parts 4, 5, with whatever is mounted thereon, including pawl 86, move backwardly to the depth of notch 91, which movement, it will be noticed, does not bring the parts 4, 5, etc., back to their first osition. This brings pawl 86 directly over ug 95 on plate lever 96, and the cams 8 and 9 will revolve with pawl 86 until finger 93 on said pawl engages with saidv lug 95, releasing the finger 92 from notch 91, when cams 8 and 9 cease to revolve and the backward throw of pawl 86 is then completed. Brake 101, secured to the frame 1, assists in bringing the cams to a state of rest. When pawl 86 is abutting against the edge of hub 90, and the finger 92 is riding on washer 88, the linger 93 in its revolution strikes the forward side of finger 94 on plate lever 96, and forces said plate lever backward against spring 99, thus preventing lug 95 from affecting the position of pawl 86, until finger 92 has entered notch 91. If lug 95 should trip pawl 86 ben fore finger92 has entered notch 91, the said finger would miss the notch, and pawl 86 would return to its original position without rotating the cams 8 and 9.

The general o eration of the machine is as follows: yBe ore starting operations, a portion of the tin foil 19 is reeled from spool 17, carried around spools 20, 21, rolls 22, 24, and to clamping jaws 26, 27.- The forward arm of lever 16 is then depressed by hand and released. This depression carries downward the free end of sprin v lever l65, which as before stated, lis secure at its movement of the forward arm of lever 16 is greater than is necessary to depressthe free end of lever 62, (which it will be remembered was automatically raised by end of gripper 45, at the completion of the previous backward motion of late 46, the spring 59 bein suliiciently sti to overcome t e weight of ever 62) the bend in spring lever 65 will straighten out to accommodate this'diflerence. End 60 of gripper 45 is thus depressedl suilicient-ly to permit of 'its being locked in this position by finger 102 A of bent lever 103, pivotally mounted at 104 upon standard 105, secured to plate 46. (See Flg. 5.) Pin 106, secured to standard 105, limits the motion of linger 102, and carries a leaf spring 107, which impinges against finger 108 on bent lever 103, thus impellino' said motion as soon as the depression of en 60 permits same to act. The release of le ver 16 permits pawl 86 to cause one revolution of cams 8 and 9, as already described. This revolution causes the following sequence of motions. Plate 46 moves across to jaws 26, 27, with gripper 45 open. Knife 32 is up and stationary, but knife 33 is depressed by the same lever 42 which carries forward plate 46, so that said plate can ride .under the lingers of jaw 26; and at the same time cam lever 31 operates to raise lever 28 with its jaw 27 thereby releasing the foil. At the forward end of the motion of plate 46, the finger 108 ofbent lever 103 strikes a 5 cam block 109 (see Fig. 3) and releases end 60 of gri per 45, and spring 59 causes the fingers o gripper 45 to seize and hold the foil firmly against plate 46. Then cam lever 43 operates to move plate 46 back to its original position, carrylng yvith it the slack of the foil 19 which has been reeled vfrom spool 17 by the forward motion just described. Just at the end of this 'backward motion, knife 33 ascends (through the agency of cam lever 43) and cam lever 40 "causes knife 32 to descend and cut off a suffi- Thus pivotally mounted on two pins 112, 112,

secured to standard 2, and normally held in horizontal position by coiled sprmgs 113, 113, and stop pins 114, 114. It will be noticed in Fig. 3 that leaf 110 is shorter than leaf 111, and that pinion 71 and the free end of arm 16 are at one side of the center of the machine. With this fact in mind it will be notedvin Fig. 2, that the section is taken so asl to pass through the spindle 7 5,v

as well as shaft 3, as is' indicated by line 2 2 in Fig. 3. The next step-is to grasp f the bottle to be operated upon,'by the body portion, place the neck upon the sheet of tin fo1l directly over the forward arm of lever 16, with the body of the bottle resting thereon, and the cork slightly pressed against the gage 115, adjustably secured in the end of shaft 3, for the purpose of regulating the position of the foil on the neck of the bottle. Then press downward on the bottle in lever 16, and immediately bent lever 65 operates to depress end 60 of gripper 45, thus releasin the foil before the bottle has exerted sufliclent pull to tear it.- The foil, which has been previously gummed, adheres to the n eck of the bottle, and descends with it, being wiped around said neck by the leaves 110, 111; the short end completely by leaf 110 and the long end but partially by leaf 111.

When the downward motion of the bottle is 'completed the neck is directly opposite disk 76, and brush 74, which are then in the positions shown in Fig. 2. Rotary motion is imparted to brush 74 by pinion 71, and said brush acts to wipe the long end of the foil upon the neck of the bottle. Just before. brush 74 completes one revolution, its lever 73 releases disk 76, as previously described, and this disk strikes a blow on the cork, crushing the free edge of the foil upon said cork. This completes the operation, and when the pressure upon lever 16 is removed by taking out the bottle, another revolution of the cams is caused; but this time by the motions necessary to cover the bottle, and not as before by hand. As soon as the plate 46 has completed its backward movement with a supply o-f foil, cam lever 31 operates to close the jaw 27, thus holding thefoil' while it is being cut and until the gripper again comes forward for another piece. It will be thus seen that after one revolutionI of the cams has placed and cut off one supply of foil, the subsequent action of the machine depends solely upon the `placing of 'successive bottles on lever 16,

and depressing same.

It will be understood that if material already coated with -adhesive be supplied to roll 17, the gluing roll 25 then becomes a moistening roll, and the glue pot would contain moistening liquid.
